iTo allwhom it concern:

"new and useful Improvements in Jersey Citv, in the county of Hudson and State of New Jersey, haveinvented certain Type- W'riting Machines, of which the following a specification. 7 g Till S lIlVQIlllOIl relates to the ribbon mechanism of typewritin "machines,and par:

ticularly to means For bringing intonsc either of a plurality of ribbons "at will.

In certain of my copending applications,

two ribbons of different colors are movable independently of one another to cover the pr ntfiig point at each type stroke. The ribbons are superposed -'or placed one in front of the other inf'fnont of. the platen,

and one of the ribbons covers andiincovers the printing point during the type strokes, while the other ribbon remains idle.

The object of the present invention is to provide simple, inexpensive and easily operated means which can readily be applied to existing machines for either bringin either ribbon into use and silencing the otier one or silencing both simultaneously, at will.

I employ two vibrators or carriers, through eaich carrier. Both vibrators I mount upon the usual ribbon vibrating lever ofthe Underwood. front strike writing machine, so

thatboth carriers rise and drop together at I further provide means' for shifting the carriers relatively to each;

the type strokes.

other, so that one ribbon may stand higher than the other, and hence be brought into use while the other does not reach theprinting 1 point. For this purpose, I provide a crossconnection between .the'upright ribbon carriers at their lower ends, and this cross-connection is directly engaged to the usual ribbon vibrating lever. Said cross-connection is loosely engaged to said lever, so that it may vibrate, one end going up while .the other goes down, whereby onev carrier is elevatedand the other depressed.

In the accompanying drawings, Figure-1 is a perspective rear view illustrating my improvementsapplied to an Underwood front strike writing machine. Fig. 2 is a sectional side elevation showing a type bar in printing position, and the type striking through one ribbon-"against the front of the I I platen. Fig. 3 is a'plan of the two ribbon Be it known that I, -EDWARD F. 'IKUNATH,

citizen of the United States, residing in carriers. Fig. 4 is a' view like Fig. 2,"but

showing the types printing through the rib- J bon. Fi 5 is a rear elevation of the ribbon carriers showing the rear carrier silenced as 1 at Fig. 4. Fig.6 is a View similar to Fig.

showing the front carrier silenced as at Fig.

. Fig. 7 is a view similar to Figs. 5 andta,

but showing both carriers silenced 'or inop f 2 .erative as at Fig. 8. Fig. '8- is a view sho'w -z 'ing the platen and the platen type-bar rib-f;

bons as at Fi 2, but showing both ribbons elevated insuiliciently to cover the printing point so that the types strike off fron Ejt-he ribbon, as at Fig. 7.

, Upon the front side of a revoluble platen 1 strike types 2' mounted upon type bars 3. In front of the platen is the usual ribbon 6, winding back and forth upon spools 7, 8,- the latter mounted on verticalv shafts 9, 10. Said ribbon 6 is threaded through an upstanding carrier 23 loosely connected to the front end of a lever 25, which is pivoted upon a shoulden-screw 26, the latter threaded into a bracket 27 fixed upon the rear side of a horizontal shift rail 2S.

Said lever 255lias an" arm 29 extending up from said pivot 26a'nd'5 provided with a laterally projecting pin 30, whereby the lever is operated during the backward and forward movement of a universal bar frame or table 21,.

In rear of the main ribbon 6', I stretch a supplemental ribbon 31 of red or other special color, which extends between spools 32, w

'33, pivoted at the extreme sides the machine, so that-the spools 7,.8, he between;

said spools 32, 33. Spools 34. 35 are mount.- ed in front of the spools 7,8, andthe endless ribbon 31 is carried therearound, as seen at Fig. 1, so that said ribbon 31 completelyincloses or surrounds the spools 7, 8 with their attached ribbon (3. The ribbon 31' may be wound in the manner set forth in U. S. Patent No. 857.288.

The ribbon 31 is threaded through rib-- "It is usual in said Underwood machine to shift'the.plate1rup. .to enable the upper case charactersto pr nt. For this purpose a shifting frame isnprovided, of which the shift rail 28 formsfa part. The platen 1 is;

journaled upon a platen frame, (not shown) -which has a roll 68110 run upon said shift rail 28. Thelatter is shifted up at the caseshifting operation, and withitrise the bracket 27 the lever and the ribbon c'arriers .23 and 40,. together withthe ribbon carried'thereby; the deep vertical slot 52 in to cover the printing point, at the type strokesis carried on thesame Whether. the platen 1s shifted up or down. At its lower end the, carrier 40 is formed with an ear or offset 69 at one side of the .lever 25,'and the carrier 23 has. an offset 70 atthe opposite side of the lever. 25; a yoke or lever 71 being pivoted at its ends to said ott'sets, as at 72, '73. Midway of its ends, said yoke 71 is formed with a ball portion 7 4, which is detachably inserted inan eye '75 usually provided upon the front of the lever 25, said ball forming a universal joint between the lever and the yoke to accommodate the vibratory movements of both. The forward carrier is provided with a finger piece 76, and when the latter is depressed, the carrier is forced down together with the ear 70 thereon, thus'vibrating the yoke 71, and raising the car (it) together with the carrier 40 to the position seen at Figs. 9 and 6. .When the finger piece 76 is lifted, the yoke 71 is vibrated in the opposite direction, so that the carrier 40 is silenced, and the carrier 23 brought up to work, as at Figs. 4 and The eye .75 in the lever serves as a fulcrum for the yoke 71 during the operation of shifting the carriers.

The carrier 40 may he provided with a vertical slot 77, and the carrier 23 may have a guide-pin 7 8 working in said" slot, thereby keeping the carrier 23 in vertical position. The pin? 8 further serves as a stop, since by engagement with the ends of said slot, it serves to limit the relative movements of the ribbon carriers, At Figs. 5, 6 and 7, the lever 25 is shown as vibrated up to the extreme limit -ofits movement at the type stroke; the types 2 printing through the ribbon (i, at Fig. 5, and

, through the ribbon31, at Fig. (i, but printing above or striking ofi from both ribbons at Fig. 7 for writing stencils. In other words, the movement of the link 71 from either-Fig. 5 or Fig. 6 position to Figi'l position is in- I suflicient to set both vibrators to ineffective positions; said vibrators at this time preferably coinciding as shown. In practice, there is suflicient 'friction between the vibrators to enable them to retain \the Fig. 7 position,

while the types are 0 erative; and thefvibration ofpthe lever 25 coes'not tend to disturb this arrangement. p e

' Variations may be resorted to within the scopeofthe invention, and portions of the im rovements may be used without others.
